Bad idea! Never take your clones when your plants are in flower. Even just one day into flower will cause mutations. check out this thread. https://www.rollitup.org/advanced-marijuana-cultivation/98902-genetics-cloning-mutated-plants.htmlive been getting mine just after i flip them to 12/12 and sex them.
or night, I think.You can clone any time of the day it doesnt matter!
